SELF-DISCI-IARGING CAB.

Application filed February 9, 1921.

T 0 all whom it may concern:

Be it known that I, RUDOLF Lonnnz, residing at Essen, Germany, a citizenof the German Republic, have invented a certain new and usefulImprovement in Self-Dis charging Cars, of which the following is aspecification.

This invention relates to self-discharging cars discharging from thebottom and having bottom flaps opening automatically under the weight ofthe load and m vable side walls resting with their lower edges upon thebottom flaps and being displaced by the latter on the dischargingoperation and pivoted at their upper edges on fixed parts of the car.The object of the present invention is to so improve self-dischargingcars of the type described as to enable a quick and reliable dischargingeven in the case of extremely bulky material to be discharged. i

One embodiment of the subject-matter of the present invention isillustrated in the accompanying drawing in which- Fig. 1 shows a sectionthrough a self-discharging car constructed in accordance with theinvention, ready for loading, and

Fig. 2 shows a similar sect-ion ot' the car in the discharged state.

The two bottom flaps B are connected, so as to admit of rotation, withthe undertrame A of the car by means of bearings a arranged at eitherside of the longitudinal middle plane of the car. The bottom flaps B areinclined toward the middle line where their respective lower edges 72bear against each other and they thus constitute a tunnel.- shaped hold.The two side walls C are sus' pended at their upper edges by means ofhinges c to the stationary end walls A? ot the car, their lower edges 0resting on the bottom flaps B. The conditions and respective dimensionsare so chosen, that the lower edge 0 of each side wall will, at anyposition which the parts may assume, be disposed nearer to the middleline of the car than the bearings a of the bottom flaps B.

When the car is ready for loading, the two bottom flaps B are connectedto each other at their lower edges 6 by means of a Specification ofLetters Patent.

Serial No. 4%,649.

locking device, such as hook b and pin 6 When the car is to bedischarged, the loci mg device of the bottom flaps B is released,whereupon said flaps, by the weight of the load, begin to swing downabout the axis oi? the bearings a and consequently open downwardly. Theside walls 0, acting likewise under t re action oi? the weight of theload, follow the movement of the bottom flaps B and swing outwarc. inthe direction indicated by the arrows 00 (F 1) until the have attainedthe position illustrated in F 2. Owing to this outward movement ot theside walls (I the space enclosed by them before the bottom flaps opened,increases so that even very bulky materials may be satistactoiily andautomatically discharged.

The discharging having been effected, the movable parts of the car arereturned into the position indicated in 1, whereupon the bottom flaps Bare again connected to each other by means of the above-mentionedlocking device.

I claim:

1. A self-discharging car having bottom flaps suspended on fixed partsof the car and movable side walls partaking of the discharging movementof said bottom flaps and suspended on fixed parts oi": car, the loweredges oi said s de walls resting upon the cor bonding bottom flap atpoints lying near to the middle plane of the car than the points atwhich the corresponding bottom flaps are suspended.

2. A self discharging car for material, dischargeable with di'llicultycomprising side members and a plurality ot bottom membersopeningdownwardly on the discharge of material from said car, said sidemembers contacting with the contiguous-1y mounted bottom members saidside members automatically opening outwardly by the action of the bottommembers when taking up a discharging position.

The toregoing specification -signed at Essen, Germany, this 27th day ofSeptember, 1920.
